Copy database file from asset

I'm using this code for copy database file from asset into /data/data/app/databases But I get this exception and apps crashes. What's problem?

Once worked!
I uninstall app each time I try my code!

 public static void copyFromAsset(Context context,String filename) throws IOException {



       try{

            // CHECK IS EXISTS OR NOT

            SQLiteDatabase dbe = SQLiteDatabase.openDatabase("/data/data/"+context.getPackageName()+"/databases/"+filename,null, 0);

            dbe.close();

        }

        catch(Exception e)

        {

            // COPY IF NOT EXISTS

            AssetManager am = context.getAssets();

            OutputStream os = new FileOutputStream("/data/data/"+context.getPackageName()+"/databases/"+filename);

            byte b = new byte[1024];

            int r;

            InputStream is = am.open(filename);

            while ((r = is.read(b)) != -1) {

                 os.write(b, 0, r);

                 Log.i("Writing", "Is processing...");

           }

           is.close();

           os.close();

        }



   }

1.The folder databases is not created at instsll of your application. Check first if it exists and create before you try to put something in it. 2. A database file often has extension .db which you are not using. 2. You put code in a catch block. But that code should also have a try-catch.

1.The folder databases is not created at instsll of your application. Check first if it exists and create before you try to put something in it. 2. A database file often has extension .db which you are not using. 2. You put code in a catch block. But that code should also have a try-catch.

1.The folder databases is not created at instsll of your application. Check first if it exists and create before you try to put something in it. 2. A database file often has extension .db which you are not using. 2. You put code in a catch block. But that code should also have a try-catch.
